Diode Laser Stacks

Product catalog summary
Horizontal Diode Laser Stacks
  • Features: These stacks offer high optical output power of 310 W continuous wave (cw), high efficiency, low divergences, a long lifetime exceeding 2 years, and high reliability.
  • Applications: Primarily used for pumping solid-state lasers and material processing.
  • Specifications: They provide a maximum optical output power of 310 W, with a center wavelength ranging from 807 to 938 nm at 25°C. The typical operation current is 92 A, and the maximum operating voltage is 8 V. Cooling is achieved with a flow rate of 2 l/min and water temperature between 15 to 35°C.
Vertical Diode Laser Stacks
  • Features: These stacks deliver high optical output power up to 300 W quasi-continuous wave (qcw) per bar, with high efficiency, low divergences, and a lifetime exceeding 1 GShot.
  • Applications: Suitable for pumping solid-state lasers, illumination, and medical applications.
  • Specifications: They offer a maximum pulse power of 900 W, with center wavelengths at 808 or 940 nm at 25°C. The typical operation current is 285 A, and the maximum operating voltage is 6.9 V. Cooling requires mounting on a cooled surface with an operation temperature between 15 to 30°C.
Diode Laser Stack in Housing
  • Features: These stacks provide high optical output power up to 780 W for long pulses, with a small, robust design, lightweight (< 60 g), and sealed housing.
  • Applications: Used for pumping solid-state lasers and medical applications.
  • Specifications: They offer a maximum pulse power of 780 W, with a center wavelength of 808 nm at 25°C. The typical operation current is 110 A, and the maximum operating voltage is 15 V. Cooling is achieved with a flow rate of 0.8 l/min and water temperature between 15 to 25°C.
General Overview: The document details specifications for various models of vertical diode laser stacks by JENOPTIK Laser GmbH, designed for high optical output power, efficiency, and reliability, with applications in laser pumping, material processing, and medical fields.
Specifications:
  • Optical Output Power: Ranges from 45 W to 120 W per bar, depending on the model and configuration.
  • Efficiency and Divergence: High efficiency with low divergence angles for focused laser output.
  • Lifetime: Greater than 10,000 hours for continuous wave (cw) operation, and over 1 GShot for quasi-continuous wave (qcw) operation.
  • Wavelengths: Center wavelengths at 25°C are available at 807 nm, 938 nm, and 976 nm, with specified variations and bandwidths.
  • Cooling Requirements: Actively cooled with specified flow rates and water quality requirements.
Applications:
  • Pumping of solid-state and fiber lasers.
  • Material processing tasks.
  • Medical applications, including hair removal.
Design Variants: Multiple designs are available, each with different numbers of submounts (ranging from 4 to 12), affecting total output power and cooling requirements.
Operational Conditions: Requires a cleanroom class 100 environment and a non-condensing atmosphere for optimal performance.
Additional Information: Specifications are subject to change in compliance with the company's quality management system. Options for different wavelengths and additional designs are available upon request.
